Title: Creating file system within file in storage technology-abstracted manner
Inventor: ROGERS ANDREW M
IPC: G06F9/445
Filed: 2004-12-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a system and method used in manufacturing computer devices, in which a single manufacturing image file contains an internal partition/file system layout into which individual operating system component packages are written.  <P>SOLUTION: The image file is independent of any particular storage technology. To generate the file, a disk image utility tool inputs a memory configuration file and a package-partition mapping file to create the partition/file system within the image file. The operating system components (package) are written into the partitions. To store (or flash) the image file data into a particular storage device, the image file is post-processed to customize the data for the particular storage device.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Cylindrical body for ink sheet rolls and intermediate connector
Inventor: INOKI HISASHI
IPC: B41J33/16
Filed: 2004-12-17
Abstract: <P>PROBLEM TO BE SOLVED: To enable a rotation driving force from an external source to be certainly transmitted to core tubes through an intermediate connector by strengthening the connection between the intermediate connector and the core tubes.  <P>SOLUTION: The intermediate connector 61 is inserted from one end of a winding-side core tube 33a, then a rib section 65 is inserted along with an inner surface 72 (a). After the tip of the rib section 65 has been abutted with an engagement protrusion 71, if the rib section 65 is further inserted, it causes elastic deformation toward the inner diameter core direction by receiving a load in the inner diameter core direction from the engagement protrusion 71. This elastic deformation gets larger as the rib section 65 is further more inserted, and becomes maximum just before the engagement protrusion 71 is fitted into an engagement hole 66 (b). If the insertion is made further from this state, the engagement protrusion 71 is fitted into the engagement hole 66 and the rib section 65 returns to the original state prior to the elastic deformation (c). Thereby, the intermediate connector 61 is firmly connected with the winding-side core tube 33a.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
